Have you climbed your family tree? Perhaps you have a famous - or infamous - relative. Find out how to fill in the branches at tomorrow’s Introduction to Genealogy Workshop, where a staff member will show beginners how to get started using census, naturalization, and passenger arrival records.

The National Archives and Records Administration, 380 Trapelo Road, Waltham. 781-663-0121. www.archives.gov/northeast
